1.mau atoa faaaoga o le bandwidth punaoa o alava opitika. Fiber ei ai tele bandwidth bandwidth (low loss band). Wavelength vaevaega multiplexing tekonolosi faʻateleina le tuʻufaʻatasia gafatia o se alava i le tele o taimi i le fiasefulu pe oʻo foi i le fiaselau o taimi nai lo lena o le tasi wavelength, faʻapea ona faʻateleina le auina atu gafatia o le alava ma faʻaititia le tau. E i ai aoga tele aoga ma tamaoaiga tau.

2. faailo manino manino faasalalauga. Talu ai ona o le WDM faiga e faʻateleina ma faʻaletonu tusa ai ma le eseesega wavelength o le malamalama, e leai se mea e faia i le fua faatatau o le faʻailoga ma le auala o le eletise modulation, o lona uiga, o faʻamatalaga e "manino" i faʻamatalaga. O lona iʻuga, o faʻailo ma foliga eseʻese lava e mafai ona tuʻuina atu, e pei o le ATM 、 SDH 、 IP ma le fefiloi feʻaveaʻiina o le tele o tautua (leo, ata vitio, faʻamaumauga, ma isi), ma isi.

3. faʻalauteleina ma faʻaleleia e faigofie ma talafeagai, tau maualalo. E talafeagai e faʻalauteleina le mafai o le opitika alava fesoʻotaʻiga polokalama e ala i le faʻaaogaina o le wavelength division multiplexer technology. I le faʻagasologa o le faʻalauteleina o fesoʻotaʻiga ma atinae, e leai se manaʻoga e suia le laina uaea opitika, naʻo le suia o le transmitter opitika ma opitika taliaina, o se lelei faʻalauteleina auala.
